The Thomeer database created is used by internally designed software, to apply these parameters for the geocellular saturation-height model for the multiltimodal pore systems in this reservoir. As a part of this process, detailed core to log integration, permeability prediction modelling, and well log quality control steps are utilized.

Thomeer parameters for a multi-pore system of a Thomeer model are determined by evaluating an objective function that measures the mismatch between the well log data and modeled data having the

study suggests that the Thomeer parameter equivalent to largest pore-throat radius, could be used as cut-off parameter for rock/pore typing of the complex, multi-modal formations in Edvard Grieg field, but future studies are needed to confirm. The rest of this thesis is organized as follows. Chapter 2 provides a short introduction to the A new relationship between air permeability and three parameters describing a pore network is presented. The parameters are normally derived from the mercury/air capillary-pressure curve but may also … Parameters in this model include: interfacial tension, contact angle, shape factor, porosity, permeability, irreducible water saturation, and displacement pressure. These 2020-12-17 · The term "petrophysics" was coined by G.E. Archie and J.H.M.A. Thomeer in a quiet bistro in The Hague. By their definition, petrophysics is the study of the physical and chemical properties of rocks and their contained fluids.

Moreover, investigations of the Thomeer parameters were performed and the analysis showed: high correlation between the Thomeer parameter equivalent to largest pore-throat radius and permeability measured by CCA. Thomeer suggested an pore geometrical factor. Thomeer suggested an empirical fit for f(G) = G -1.333. Swanson's parameters (SA,pA) are mercury filled pore volume and capillary pressure at the maximum curvature point A in the pressure at the maximum curvature point A in the mercury capillary pressure curve.

(2008) as objects or combinations of objects that are present in the 3D space of the Thomeer pore-system parameters. Porositons are a new PRT object type; other PRT objects are clusters, trends, and surfaces. By clustering the Thomeer parameters of each MICP data, different rock types can be distinguished.

Porositon combinations are used to construct meaningful petrophysical rock types. Petrophysical rock types (PRTs) are defined by Clerke et al. (2008) as objects or combinations of objects that are present in the 3D space of the Thomeer pore-system parameters. Porositons are a new PRT object type; other PRT objects are clusters, trends, and surfaces.

We observed four distinct and separable modes (Figure 5) and fitted each with a Gaussian distribution, termed a Porositon. Thomeer (1960) used three parameters (the extrapolated displacement pressure P d, the percent bulk volume occupied by mercury at infinite capillary pressure B ∞ and the pore geometrical factor G) hyperbola function to fit the MICP curve, thus the derivative of Thomeer hyperbola was used as PSD function. The Expectation-Maximization algorithm for Gaussian mixture model was utilized to obtain three controlling parameters for the calculation of Thomeer parameters, namely the extrapolated displacement pressure, the percent bulk volume occupied by mercury at infinite capillary pressure and the pore geometrical factor. The details in position and shape of the hyperbola are determined by the three Thomeer parameters: P d, which is the “minimum entry pressure” or “threshold pressure”, related to the largest connected pore throat diameter; G is the “pore geometrical factor” related to the range of pore throat diameters and B v ∞, which is the “fractional bulk volume occupied” by mercury at P c =∞.

When the input common mode range covers both power supply rails 0 V and VCC, it is a rail-to-rail input stage. Our Thomeer parameter databases can be manipulated to extract PRTs, correlations and statistics for each reservoir. Clerke has defined PRTs as objects in the three dimensional space of Thomeer parameters.

A comparative study among most popular soft computing techniques is presented using a large dataset published in literature describing multimodal pore systems in the Arab D formation.
